M74HC14. Hex Schmitt inverter. Features. Description

Transcription

1 Hex Schmitt inverter Features High speed: t PD =12 ns (typ.) at CC = 6 Low power dissipation: I CC = 1 μa (max.) at T A =25 C High noise immunity: H = 1.2 (typ.) at CC = 6 Symmetrical output impedance: I OH = I OL = 4 ma (min.) Balanced propagation delays: t PLH t PHL Wide operating voltage range: CC (opr) = 2 to 6 Pin and function compatible with 74 series 14 DIP-14 TSSOP14 SO-14 Description The is a high speed CMOS hex Schmitt inverter fabricated with silicon gate C 2 MOS technology. Pin configuration and functions are the same as those of the M74HC04 but all the inputs have 20% CC hysteresis level. This, together with its Schmitt trigger function, allows the device to be used on line receivers with slow rise/fall input signals. All inputs are equipped with protection circuits against static discharge and transient excess voltage. Table 1.

2 Maximum rating 2 Maximum rating Stressing the device above the rating listed in the Absolute maximum ratings table may cause permanent damage to the device. These are stress ratings only, and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents. Table 4.

C PD is defined as the value of the IC s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to test circuit). Average operating current can be obtained by the following equation: I CC(opr) = C PD x CC x f IN + I CC /6(per gate). 5/14

5 Package mechanical data 4 Package mechanical data In order to meet environmental requirements, ST offers these devices in ECOPACK packages. These packages have a Lead-free second level interconnect. The category of second level interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. ECOPACK is an ST trademark. 7/14
